C1 Offset and Letterpress Proofer – C1, C1-5, C1-7
Dedicated IGToffset and letterpress ink proofer. Produces consistent ink film thickness repeatedly.Has a built in inking unit. Selectable printing pressure and speed. Ideal for quality control of offset printing ( conventional or UV ) and letterpress inks. Variety of models with 35 or 50 or 70mm wide print area.
The C1 range of printability testers is an efficient and reliable way of making colour strips with offset inks to a known ink layer thickness.
Results are consistent and reproducible and offer a potential cost saving because of the high degree of correlation with on-press results.
Designed for intensive use over long periods, they are sturdily built, simple to operate and can print on a wide variety of coated and uncoated materials including paper, board, plastic film, cellophane, laminate and metal.
Applications:
The C1 range can be used:
- for testing printing quality, gloss, mottle and set-off; visual appraisal; colour matching and measuring colour with colour measuring systems and spectrophotometers
- for taking density measurements including colour and density tolerances, degree of coverage, wear resistance, scratch resistance, flexibility, adhesion and gloss, ink transfer (in g/m2), light fastness and resistance to chemicals
- in the printing ink, paper and board, print, metal, plastics and packaging, resin, lacquer, coatings, cosmetics and electronics industries

Features:
- Simple operation – inking and printing in one instrument
- Repeatable, reliable and reproducible results
- Low cost
- Lightweight
- Easy to clean
Operation:
- C1 printability testers consist of an inking section and a printing unit
- The two driven aluminium drums and a removable rubber top roller evenly distribute the ink within
- 30 seconds and the printing disc has an inking time of 15 seconds
- The substrate is attached to a substrate carrier, which also acts as a printing disc mount during inking
- The printing force can be set in 19 steps between 100 and 1000 N and the print is made automatically
